LIQUID MIXING AND DELIVERY APPARATUS.

Specification of Letters Patent.

Patented Mal. 23, 1920.

Application filed March 6, 1917. Serial No. 152,717.

To all whom it may concern:

Be it known that I, HARRY S. CORNISI-I, a citizen of the United States, residing at Chlcago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid Mixing and Delivery Apparatus, of which the following is a specification.

My invention relates more particularly to apparatus for dispensing drinks which are made up at the sales-counter by mixing a suitable proportion of flavoring syrup with water. It is desirable in apparatus of this kind that the water and syrup be dispensed from the original bottle or package without transfer to other containers, in order to avoid the possibility of contamination or the introduction of impurities, and it is a practical necessity that the apparatus be adapted to automatically mix the syrup and water in the same definite proportion, which may be regulated at will by the operator. As it is further of advantage to feed the syrup and water by gravity it is necessary in order to avoid variations in the proportions of the two liquids that the heads of the respective liquids at the faucet be maintained constant. My improved construction takes care of all these various requirements.

In the accompanying drawing and in the following specification I have described a preferred form of apparatus embodying my invention; but it is to be understood, however, that the specific disclosure is for the purpose of exemplification only, and that the scope of the invention is defined in the following claims in which I have endeavored to distinguish it from the prior art so far as known to me without, however, relinquishing or abandoning any portion or fea ture thereof.

In the drawings Figure 1 is a vertical sec tion of a preferred apparatus embodying my invention; Fig. 2 an enlarged vertical section of a drawoif faucet thereof; Fig. 3 a plan view of the same; and Fig. 4 a plan of a detail.

The same reference character is applied to each part wherever it may occur throughout the several views.

Referring to Fig. 1, an ice-box or casing is shown at 5, the wall 6 of which are as usual hollow but may be filled with any heat insulating material as felt or the like. The

ice-chamber 7 is closed by a cover 8, which forms the bottom of an air-chamber 9 mounted upon the ice-box for a purpose which will appear. Access to the ice-box for the purpose of inserting ice is provided through a door 10.

Within the chamber 9 is mounted a cup 11 which extends through the top 12 of said chamber, and is formed with a flaring rim 13 to form a seat for the water bottle 14:

which, when the article is in use, is inverted in said cup with its shoulder resting upon the rim 13 and its mouth or neck open. 7 A reservoir l5 of a capacity greater than the amount of any one delivery of water is in communication with the bottom portion of the cup 11 through a channel 16, and from the reservoir 15 a conduit or pipe 17 leads through the ice-chamber 7 where it is formed with a number of coils 18 and from said ice chamber to the faucet 19.

The faucet 19 comprises a body portion 20 anda rotary valve 21 which controls two passages from the cooling coil and syrup cup respectively. Upon the faucet body is mounted an open-topped reservoir 22 of a capacity in excess of any one delivery of syrup, to which is connected cup 23 similar to cup 13, and having a flange 2a which supports a bottle 25 of syrup in an inverted position, and with its shoulder resting upon said flange. Cup 23 is connected to the reservoir 22 by a passage 26, and reservoir 22 communicates with a chamber 27 in the body of the faucet by means of a neck 28. A passage 29 leads from chamber 27 to a port 30, controlled by the rotary valve 21, and a pipe 31 leads from the cooling coil through chamber 27 but not communicating therewith to a passage 32 in the faucet body and to a' port 33 likewise controlled by the valve. The valve is shown in plan at Fig. i and on a slightly enlarged scale. It is provided with ports or passages 34, 35 which may be brought simultaneously into register with the ports 30, 33 in the faucet body respectively by turning the handle 36 of the valve, and in this position permits the flow of water and syrup simultaneously into the nozzle 37. A short tube 38 is anchored to a bracket 39 in the nozzle in register with the port 30 and is carried at 40 to the reduced opening of the nozzle so that the flow of water assists to some extent the flow of the more sluggish syrup. In order to regulate the proportions of the respective liquids accurately a screw bolt ll is threaded into the body of the faucet in such position that its end42 may extend into the water channel 32 to choke, and regulate the same; Passages 43, 44: communicate with the syrup chamber in the faucet and with the water passage respectively and terminate in turning. plugs 45, 46 respectively, which may be used when it is desired to draw ofl either liquid unmixed. with the other.

an' and again rises as more liquid flows from the bottle following-the entrance of air. This irregularity ofaction is found to very materially affect the proportions of water and syrup which flow from the faucet, so that one glassful of the mixture will contain a different proportion'of syrup from the next.

By providing the reservoirs 15 and :22, however, of greater capacity than the amount of liquid of any one delivery, with their tops open to atmospheric pressure, I provide for an equalization of the flow which maintains the head of the liquid substantially constant,

' and" relieves it of the effect of the gurgling action heretofore mentioned. Therefore the proportlon of syrup to water is always maintained constant except as adjusted by means of the screw ll.

I claim :7

1. In a liquid dispensing apparatus, a support, a cup mounted on the support, a bottle on the support in inverted position, the neck whereof projects into the cup and is sealed by liquid therein, an open-topped reservoir mounted on substantlally the same level as the cup and communicating therewith at a point below the mouth of the bottle, and a faucet connected to the reservoir.

2. In a liquid dispensing apparatus, a support, a cup mounted on the support and adapted to receive a bottle of water in invert-ed position and to form a liquid seal therefor, a reservoir communicating with the cup, a cooling coil connected to the reservoir, a mixing faucet connected to the cooling coil, a second cup adapted to receive a syrup bottle in inverted position, a reservoir in communication with said cup and a connection from the reservoir to the mixing faucet.

In a liquid dispensing apparatus, an ice box, a cup mounted thereon and adapted to receive a bottle of water in inverted position and to form a seal therefor, an open-topped reservoir in communication with said cup, the cup and reservoir being mounted above the ice box, a coil connected to the reservoir and extending through the ice box, a mixing faucet to which the coil is connected, a second bottle-receiving and sealing cup and reservoir mounted on the faucet, and connections from the last said cup to the reservoir and from the reservoir to the mixing faucet.
